Description
Coordinate Y:
y1: Real-time value of coordinate y1
•
y2: Real-time value of coordinate y2
•
dy: Automatically calculated value range.
•
The formula is as follows:
dy = y2 - y1
y(t1): Real-time value at the cross point of coordinate
•
t1 and selected curve.
y(t2): Real-time value at the cross point of coordinate
•
t2 and selected curve.
dy(t): Automatically calculated real-time value range.
•
The formula is as follows:
dy(t) = y(t2) - y(t1)
Displays real-time frequency value of the horizontal cur-
sor coordinate in the chart.
Displays real-time amplitude value at the cross point of
the horizontal cursor coordinate and curve.
Selects a curve to display in the chart.
Time domain chart:
•
A maximum of six curves can be simultaneously dis-
played in the chart.
